1  Uses ${{\mathit \Xi}_{{b}}^{0}}$ $\rightarrow$ ${{\mathit \Xi}_{{c}}^{+}}{{\mathit \pi}^{-}}$ and ${{\mathit \Xi}_{{c}}^{+}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays. The measurement comes from the mass difference of ${{\mathit \Xi}_{{b}}^{0}}$ and ${{\mathit \Lambda}_{{b}}^{0}}$.
2  Uses ${{\mathit \Xi}_{{b}}^{0}}$ $\rightarrow$ ${{\mathit \Xi}_{{c}}^{+}}{{\mathit \pi}^{-}}$ decays.
3  Measured in ${{\mathit \Xi}_{{b}}^{0}}$ $\rightarrow$ ${{\mathit \Xi}_{{c}}^{+}}{{\mathit \pi}^{-}}$ with $25.3$ ${}^{+5.6}_{-5.4}$ candidates.
